Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws
Hey friend, we're detecting that you're an American visitor and want to thank you for coming to PlumbersTalk.net - Here is a link to the American Plumbing Forum. Though if you post in any other forum from your computer / phone it'll be marked with a little american flag so that other users can help from your neck of the woods. We hope this helps. And thanks once again.
